This application is a "continuation-in-part of my coapendingpatent applicationonstorm window framefSerial No."681;245 filed July 3, 1945, .now Patent Number2,504,7(l0.

In the above mentioned co-gpen'ding patent app1ica-tion,'Serial"No. 681245, there is disclosed a storm window frame .and several modifying sectionsvand means vfor positioning andretaining these modifyingsections in the said frame. L'I'hepresent invention relates to the same construction with the iexceptionof the meanswfor retaining the modifying sections in the storm window-"frame.

.In the aforementioned co-pending patent application, we'dgemembers were employed to disr areasifor the reception oftg'lazed sash positioned rtherein. ILlZ'he present'inventionrelatesito alsimpli-fied double hung storm sashan'd morepaittim ularly to the means employed in assemblingithe several component parts thereof and locking them in assembled position to form the completed frame.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it

being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scopeof what is claimed withoutdepartingfrom the spirit of the'invention.

' The invention is' illustrated in the accompanying'drawing, wherein: l

'By referring to the "drawings'and Figures 1 and 2 in particular it will be seen that a-double hung storm "sash has been disclosedin'position 'on-a-window casing =|ll,the sill ll thereof supporting the lower 'portion of the double hung stormsash-an'd'the exterior pertionof-the double hung storm sash overlapping the casinglfi.

The fdouble'hung'storm sash comprises a main frame of" rectangular shape to imatchithewindow opening. in which it'is-installedan'dis'formed of three "extruded metal shapes. The sidersections [2 of the mainframe are formed of one extruded shape as shown inuenlarged cross sectioninijFigure 4 ofthe drawings. Thertoprsection is of the main frame is formed of a different extruded metal shape, as shown in Figured ohthe. draw-- ings. and the bottom section IA of the .main

frame is formed of a still different extruded metal shape, asshowninFigure 5 of the draw lngs. l 7

Each off'the three extruded metal shapes l2, l3, and M .has an extending surface flange, "an edge of which is adapted to overlie the window casing I 0,, and each of ithesextruded metal shapes (2, {3 and 314 l have longitudinally, extending. T-

hea'ded ribs 15, f6 and fl, respectively, itbeing observed that the T-headedformation on the ribs I 5 and [6 are similar in size and shape while the T-headed formation on the rib I! includes an inwardly extending offset flange I8. The extruded metal shape I2 from which the vertical side sections of the main frame are formed has a pair of longitudinally extending, inwardly turned flanges l9 and 20 which are adapted to be distorted at intervals as illustrated in Figures 6 and 7 of the drawings and hereinafter described in order to retain modifying shapes 2| and 22 in the side sections of the main frame to define vertical channels in which double hung sash 23 and 24 may be positioned. It will be observed that the sash 23 is normally located in lower inner position in the main frame and slidable vertically therein in the channel defined by the modifying shape 22 heretofore referred to. The upper outer sash 24 is positioned in the main frame so that it rests on the upper ends of the modifying shapes 2|, the upper ends being indicated by the numeral 25 in Figure 2 of the drawings.

The extruded shape I3 is similar to the extruded shape I2 with the exception that it has a single longitudinally extending flange 26, the outermost edge 27 of which is inwardly turned and this section is used as the upper most portion of the rectangular main frame and forms, in conjunction with the fiat surface flange of the shape I3, an area for the reception of the upper edge of the upper outer sash 24. The lower section I 4 of the main frame is similar in overall appearance to the extruded shapes I2 and I3 heretofore described and includes a surface flange with an inturned auxiliary flange 25 formed thereon replacing, in effect, the modifying shape 2| heretofore referred to in connection with the side sections I2 of the main frame. The T- headed extension has the additional flange I8 formed thereon which defines with the rest of the shape a transverse channel for the reception of the lower edge of the lower inner sash 23. It will thus be seen that by utilizing the distortable flanges I9 and 20 of the extruded shape I2 the modifying shapes 2| and 22 may be locked into permanent engagement with the shape I2 and thereby form vertical side rails of the main double hung storm sash frame suitable for receiving the sash 23 and 24 in double hung relation therein.

It will also be observed that the sash 23 which is the inner lower one of the two sash is slidable vertically so that it can be opened for ventilation. The sash 24 is not slidable vertically but is positionedin more or less fixed relationship in the upper outer half of the frame with its upper end in engagement with the upper extruded section I3 as heretofore described. Its lower edge rests on the upper ends 2|A of the modifying shapes 2|. 3

In substituting a screened sash for the sash 23 it is lifted vertically until positioned in the upper half of the frame from whence it may be directly removed. As the modified members 22 extend vertically only approximately onequarter of the total vertical distance of the main frame.

By referring to Figures 6 and '7 of the drawings the means of positioning the modified shapes 2| and 22 in the frame may be seen and by referring thereto it will be-observed that a wrench 28 has been illustrated which includes an offset portion 29 and a handle 30 and has a head comprising a pair of offset shoulders 3| formed in axial alignment with the handle 30 of the wrench 28. The wrench 28 is employed in distorting the flanges I9 and 20, as illustrated herein, and is positioned with the offset shoulders 30 in longitudinal alignment with the flanges I9 and 20 and then turned as by moving the wrench 28 one-quarter of a revolution thus bringing the offset shoulders 3| into crossways position where they force the flanges I9 and 20 away from one another and into engagement with the modifying shapes 2| and 22 heretofore referred to. When this operation is performed at intervals as shown in Figure '7 of the drawings, the modifying shapes 2| and 22 are securely locked in permanent engagement in the frame. This method of modifying the main double hung storm sash frame is inexpensive and practical and results in an attractive weather-tight construction particularly adapted for storm sash constructions.

It will thus be seen that a double hung storm sash has been disclosed which includes a main frame of lip-type capable of overlying the casing I0 of a dwelling house window, for example, and capable of receiving therein the sash 23 and 24 or the sash 24 and alternate screen sash replacing the sash 23. The window is capable of relatively inexpensive fabrication and assembly and it will be observed that it includes a sash construction novel in the art and set forth in my co-pending patent application Serial No. 693,275, filed August 27, 1946, Patent No. 2,505,553, issued April 25, 1950, on Glass Framing Construction.

Having thus described my invention, what I claim is:

1. Frame element construction for storm window comprising: a body member including a U- shaped channel; a pair of ribs extending from the web of said U in substantially the same direction as the flanges thereof to form three parallel channels; a modifying member in each of the outermost of said channels and adapted to receive the sash of said storm window, said modifying members each having a shallow groove along that side thereof which faces the other modifying member and adjacent the free edges of said ribs, said ribs being substantially parallel with each other throughout the major part of their respective lengths and having a plurality of independent offset portions of each thereof extending out from the plane of each of said ribs toward the respective mutually adjacent modifying members and into the said respective shallow grooves thereof for locking said modifying members to said body part.

2. The article described in claim 1 wherein said offset portions are opposite each other.
